I have completed a few projects - sensors and an ADC circuit - and I find myself often connecting discrete boards together by tediously soldering wires to break-away headers like those below.
I worry about poor connections and the time it takes is excessive.
What are some good, flexible go-to prototyping connectors? I am considering getting some RJ45 connectors and using old cat 5 cable, but they aren't 0.1" spacing friendly, which makes prototyping with them harder. (Do 0.1" compatible RJ45 connectors exist? Could I rig these up anyway?)
I realize this is highly dependent on the application but I was hoping to get a solution for the general case. Or maybe soldering ribbon cable to headers is the way to go.
For a little more information, my current projects have involved carrying a ~2v signal ~1m to an ADC, carrying 1MHz SPI ~0.5m between an ADC and a PI, as well as carrying around 3-5V power and ground - so nothing terribly fancy.
Update: I went with IDC connectors (2x5 pin and 2x20 pin) and I am happy with this decision.
